A person (or conglomerate of two persons who are virtually indistinhuishable as individuals) who is so far up his or her own (or their own collective) arsehole their own mother wants to run them down.

That sanctimonious git takes pictures during a group holiday and then tries to charge for them even though everyone else is sharing their pictures and then has the gittishness to get all high and mighty when someone uses one of the pictures on their facebook profile.

I cant believe that sanctimonious git - "failed to do the right thing"!?!?!
